IEC 61850 QoS

Critical packet prioritization

  • Communication packets can be assigned different priorities, depending on their importance
  • Packet types: GOOSE, SMV, PTP
  • Packet priorities: high, medium, normal, low







VLAN Technology

Enabling efficient and reliable communication

  • Trunk traffic reduction
    Removing bottlenecks on the trunk links requires a careful analysis to correctly configure the bridges in the network. The traffic can be filtered or restricted to specific domains in the network by VLAN
  • Traffic filtering
    To segregate traffic flow throughout the network
  • Device performance improvement
    Reduce the number of messages that end devices need to process
